ssh2.shell:// ssh2.exec:// ssh2.tunnel:// ssh2.sftp:// ssh2.scp:// PHP 4.3.0 and up (PECL)
- ssh2.shell://user:pass@example.com:22/xterm
- ssh2.exec://user:pass@example.com:22/usr/local/bin/somecmd
- ssh2.tunnel://user:pass@example.com:22/192.168.0.1:14
- ssh2.sftp://user:pass@example.com:22/path/to/filename
Note: This wrapper is not enabled by default In order to use the ssh2.*:// wrappers you must install the » SSH2 extension available from » PECL.
In addition to accepting traditional URI login details, the ssh2 wrappers will also reuse open connections by passing the connection resource in the host portion of the URL.
Example #1 Opening a stream from an active connection
<?php
$session = ssh2_connect('example.com', 22);
ssh2_auth_pubkey_file($session, 'username', '/home/username/.ssh/id_rsa.pub',
'/home/username/.ssh/id_rsa', 'secret');
$stream = fopen("ssh2.tunnel://$session/remote.example.com:1234", 'r');
?>
